useful Loom, of which the followingl is a j specification.

This invention relates to a loom suitable for weaving all'l kinds'ot fabrics and this case is a division of' my Patent No. 943,028 granted on the 144th day of lfiecember 1999, on an application Iil'ed duly 24, 1908, Serial No; 445,155.

The principal objects ofthis invention are to provide improvements of such a character f that the construction of the loom: will he I great-ly simplified and the expense of rnanu` factoring' correspondingly decreased; that the repairs will be materially lessened so that a loo-rn fixer can keep a larger number; of looms in repair; that the loom will liei capable of operating at a higher speed; that" there will be fewer occasions on which the loom will be stopped and the duration of stopping will be short-er so that the production will be increased in these ways in addition to the increase due to the higher speed;

and that in the simpler types of looms an at tendant can operate a larger number.

This invention also coin rise's im roved driving connections where' y the the shuttle should break when the loom is' running,l the loom will bunt or st'op on that pick, and when it stops it connects the friction shaft above mentioned in such a way as to pull the lay bacia to its dead center, so that all the weaver has to do is to ull out the broken pick, throw a shutt e back 1iving` motion can be connected up with the rest of the machine in such a way that'w'vhenl the' vthrough the shed, and the'machine is then read to start up without'losing time, no manipuatior of the head motion' being rem quired.' 0n the other hand if the operator stops the loom with the lay up to 'the cloth sistance as is' ordinarily the case, but" he can .operate a finger or lever above the harness which will connect the lay with the friction shaft so as to reverse it to the dead center.

Further objects of Athe invention are to p'rovide eili'cient means whereby the independentoperation of several of the arts ot `the loo'rn Will be facilitated, and or this purpose the driving shaft has a loose pulley or the'like whereby the lathe, head-motion, I.pick-out motion and box motion can he oper ated independently of the drivin' shaft. In, order further to carry out this i ea, a crank: shaft, an auxiliary shaft and an intermediate shaft are provided, the intermediate shaft having meansv for connectin Y the loose pulle with the auxiliary shaft an for causlng tie intermediate shaft tobe 'rotated' by the loose pulley, and the intermediate shaft being provided with independent operatine" means for connecting it with the crank sha t so that either the auxiliary shaft or crank shaft, or both, can be operated from the loose pulley independently of the driving' shaft. The head-'motion preferably is operated from the crank shaft but means is'provided whereby it can be o erated by the aux iliary shaft when the att'er is connected with the loose pulley, and the auxiliary and crank shafts can be driven independently ol.l each other from the pulley. Reference is to be' had to the accompuzmy ing drawings, which show one form of the invention as applied to av broad heavy' motion and driving connections therefor and and wishes to reverse to dead center, he door .ff v-no't'have to push the lay back against the rc liti' for the head motion. Fig. 4 is a view from the end of the loom showing part of the pick-out motion and driving connections for the head motion. Fig. 5 is a plan of a handoperated clutch and connected mechanism. Fig. 6 is afront elevation of a cam and connected mechanism constituting part of the pick-out motion. Fig. 7 is a fragmentary plan showing connections for throwing the pick-out motion into and out of operation. Fig. 8 is a plan of the driving mechanism partly in section. Fig. 9 is an elevation thereof partly diagrammatic showing the connection of the shipper stop motion and the like with the driving mechanism. Fig. 10 is a plan'showing a portion of the stop motion, and Fig. 11 .is an end elevation showing the rest of the stop motion.

The loom is designed to operate without a so-called tight pulley, the power being ap` plied through a loose pulley 30 which receives the driving belt and which is mounted to freely rotate on the driving shaft 3l. The powerl is transmitted directly to this driving shaft, from this loose pulley by means of a clutch which consists of a slotted disk 32 keyed to the shaft and having radially sliding dogs 33'eXtending through the slots into the loose pulley and adapted to be forced against the walls thereof by means of a double wedge block 35 which acts directly on lthe dogs to clutch the pulley and operates levers 34 for withdrawing the dogs inwardly when the Wedge block moves back. The wedge block is operated by a lever 36 or the like. This lever is shown as designed to be operated by a swinging lever 37, link rods 38, and shipper handle 39 or in any other convenient manner. On the driving shaft is mounted a bevel pinion 40 which preferably is driven on to a tapered square end on the shaft so that it Will not Work loose in operation. This pinion meshes with the driving gear 4l which preferably has removable teeth 42. These teeth are shown as made vin pairs and bolted or otherwise secured removably to the base of the gear so that if one or more of them break they can readily be replaced by new ones Without dismounting or replacing the whole gear. This driving gear is mounted on the crank shaft 43 which operates the machine and which has links 44 connected with the lathe for moving it in the usual way. A bearing 45 for the crank shaft is provided with an end bearing for a friction shaft 46. This friction shaft is provided with a bevel friction disk 47 slidingly keyed thereon and adapted when pushed backward on the shaft 46 to engage a corresponding friction surface 48 on the rear of the main friction gear. The shaft is provided also with a second bevel friction wheel 50 fixed thereon and loose pulley and with a friction wheel 52 on a shaft 53. When the lever 39 is thrown to force out the wedge 35yto stop the machine it also acts through a link 54 and lever 55 to throw the friction wheel 50 into engagement with the friction surface y51 and Wheel 52 which will cause the shafts 46 and 53 to rotate while the driving shaft is at rest. If while the machine is stopped it is desired to turn'the crank shaft, it 1s necessary-only to turn a small lever or finger 60, which operates through link connections 6l to turn a lever 62 and push the friction wheel 47 into engagement with the friction surface 48 so that although the loose pulley is not operating the driving shaft, this shaft can be turned by the loose pulley through the shaft 46. If upon stopping the machine, the lathe is lfound to be forward, the lever 60 is pushed down long enough to cause the lathe t0 be swung back. This occupies only an instant of time and is of great assistance to the operator as in the heavier types of looms it requires considerable force to push the lathe back.

This invention isV shown in connection with an improved stop motion which acts in such away that the loom will stop with the lathe back. This stop motion is shown as comprising a bracket 65 on the breastbeam 66 and a stop motion rocker 67 on the bracket. On the lathe 68 is pivoted a tongue 69 normally held up by the filling thread through connections 70. When the filling thread breaks these connections and tongue are permitted to drop so that the tongue 100 engages the upper end of the rocker 67 dur- .ing the next forward motion of the lathe -When the lathe starts back there is no longer any force acting to hold the wheel 47 against the friction surface 48. Consequently the lathe will stop at the end of the back stroke.

Near the end of themachine the crankshaft 43 has a gear 8O meshing with a gear 120 8l on a head motion driving shaft 82. This shaft drives an upright shaft 83 through bevel gears 84. One of the gears 84 runs loose on the shaft 83 and is connected therewith by a clutch 85 which is operated by a 125 yoke 86 and a lever 87 adapted to be contrQlled by a shaft 88 having a handle 89 on the outside of the frame 90 of the machine.

A spring 91 normally tends to hold the shaft 88 in such position that a pin 92 130 ing the operation of the machine from the main crank shaft 43, the box motion will operate regularly, and when the power 1s shut off from the main crank shaft 43, the auxiliary shaft 53 will still be turning and consequently when the clutch 86 1s thrown in, the shafts 83 and 114, with the box motion, can be operated by power simply by throwing in the clutch handle 89.

From the description which has been lgiven, it will be seen that the above mentioned advantages can be secured in a very simple manner, and can be applied to practically all types of looms.
